Late last year, I wrote about how my credit card pays me cash. I recently ran across a discussion on our Credit Cards discussion board, though, where I learned that compared to some of my fellow Fools, I'm just a piker.

To back up a bit, in my earlier article I explained:

I'm currently using a credit card that gives me 1% back on all my purchases and on some [such as gas], I get 5% back. Over the months, these little rewards add up. I recently cashed in a check the card sent me for $263 -- not bad, eh? Not only do I get the convenience of paying for most things with plastic -- I even make money on the deal.

Well, here are some snippets from our board discussion:

To the question, "So, what did you make last year on your credit card?", NaggingFool reported, "Last year around $600, this year it will be over $1,000."

Booa reported "a household total of about $300 in about a year."

Linanil chimed in: "Last year, I received around $700 in cash back from cards." She added that she paid several hundred in interest as she was paying off debt. Overall, thanks to the cash-back feature, she came out ahead by $100. As she gets the debt under control, her cash back will represent pure gravy.

4inthefamily took advantage of long-term accumulations possible on cards that help you buy cars: "We cashed in our Driver's Edge rebates this year when [my dear husband] bought a motorcycle. That was $1,359 -- but was admittedly accumulated over three years. I received about $200 cash back on another card. I used my Old Navy card when buying my kids' school clothes and received 20% off. I also used my Kohl's card when making some clothing purchases partway through the year and received 20% off."

Concordiadiscors, like me, didn't feel so impressive: "We're kinda slacking so far this year. Between cash back and gift cards, we've only made around $250. Guess I'd better go drive around in circles so I can rack up more of that sweet, sweet 5% on gas purchases."
